  • Patent number: 6769559
    Abstract: A venting plastic closure for use with an associated container includes an outer plastic cap having a top wall portion and an annular depending skirt including an internal thread formation. A disc-shaped sealing liner is positioned on the inside surface of the top wall portion for creating a top/inside seal with the associated container. In order to facilitate venting of gas pressure from within the container, and to facilitate removal of the closure from the container by consumers, the closure includes one or more positive stop elements which engage the container after the sealing liner of the closure has been sealingly engaged therewith. The stop elements act to limit the degree of sealing engagement between the sealing lines of the closure and the finish of the closure.
